Watch the heat input and the interpass temperature, overheating duplex upsets the ferrite to austenite balance in the weld. Store the wire dry and do not leave an open spool in the feeder overnight, the core takes up moisture. Do not shorten the stick-out too far, a flux-cored wire needs resistive preheating so the core melts in time. Thinner diameters suit root runs and thin sheet, thicker ones the fill passes.
